FOUNTAIN BRUSH.

Application filed May 2O,

My invention relates to fountain brushes and refers particularly to brushes of the described character in which air in conjunction with a paste or liquid may be forced between the hairs or bristles of the brush.

One of the objects of the device of my invention is a brush, as for instance, a tooth brush or shaving brush, so constructed that both air and a suitable paste may be forced outwardly of the brush during its application.

Notwithstanding the many suggested forms of tooth brushes, considerable difficulty is experienced in reaching all of the crevices within, and spaces between the teeth, resulting in a deposit of matter therein unaffected by the' employed dentrifrice, thus creating an unhygienic and unhealthy condition.

The device of my invention overcomes this difliculty and presents a means whereby the tooth paste or tooth powder is forced into the crevices and spaces through the medium of a compressed air current created by the user.

A further advantage of my device consists in the forcing of such an air current through the teeth crevices and spaces, thus allowing` of the oxidation edect of air upon matter deposited therein.

A further advantage of my device is that the air current will dislodge and remove matter deposited within the crevices and spaces of teeth.

The device of my invention is also valuable when in the'form of a shaving brush. Minute air bubbles are usually positioned at the base of each hair, the displacement of which is essential before the shaving soap lather can reach these base portions of the hair, while these may be dislodged in part by means of an ordinary bristle shaving brush, or by continued hand massage, a large proportion still remain, thus making 4the shaving operation unsatisfactory.

The device of my invention overcomes this diiiicult-y and presents a means whereby these air bubbles may be removed by a pressure air current during the application of the soap to the skin, thus rendering the shaving operation more effective and pleasant.

While I prefer that my device have a massaging or olishing, element within the bristles of the rush in order that its effects 1926. Serial No. 110,314.

may be enhanced, such a device is not necessary.

The above and other valuable features of my device will be evident upon a consideration of this specification and its'accompanying drawings.

ln the accompanying drawings illustrating modifications of the device of my invention, similar parts are designated by similar numerals.

Figure 11 is a view, partly in section, of a modification of my device.

The device of my application, as shown in Figures 1 to 10 inclusive, comprises a nonpliable hollow handle 20, having a plurality of openings 21, 21 and having the perforated upper' shoulder 22 and the lower curved shoulder 23.

Within the handle 20 is a rubber receptacle,`or bag, 24, open at both ends, the lower end having an enclosed wire 25, fitting within, and maintained within, the shoulder 23. The bag 24 has the Hap-valve 26 capable of allowing the entrance into and preventing) the exit of air from the bag.

- Within the air-bag 2li is a paste receptacle, or container, having the annular side 27 which is soldered, or otherwise attached, to the flange 28 of the base 29, the base 29 having an opening 30 therethrough. llhe upper portion of the side 27 is contracted into the interiorly threaded neclr 31. Within the paste container is a vertical spiral member 32 ixedly attached to the flange head 33 of the revoluble pin 88, and passing through an elongated opening 34 of the slidable disc,

`of the handle.

In assembling the lower portion of the handleand contained members, the bag wire 25 is placed wit-hin a recess in the base 29 and the `handle shoulder 23, the collar 39 is positioned and the pin 38 is passed through the opening 40 of the exterior revoluble member 4l and attached thereto by -means of the pin 42.

vIn assembling the upper portion of the handle and contained members, the edge of the bag 24 is placed between the perforated shoulder 22 and the perforated shoulder 7l of the side 2,7.

A handle extension 45 has the restricted f member 46 capable of placement between the extension 47 of the side 2O and the flange 22. The upper portion of the handle extension 45 has the shoulder 48 andthe exteriorly threaded portion 49. An opening, or conduit, 50 is within the handle extension 45.

lVithin the conduit 50 is a tubular member 5l, the lower edge of which carries the exteriorly threaded head 52 and the upper end of which carries the head 53 having openings 54, 54, therein. A, pin 55 fixes the y head 53 -to the tube 51.

A brush holder 5G is capable of threaded engagement with the threaded member 49 of the handle extension 45 and has a conduit 57 therein. VJithin the conduit 57 is a tubular member 58, the lower end of which is capable of tight fitment around the cone extension 59 of the tube 5l.

AWithin a chamber G4 of the brush holder 56. is `threaded a member 5l `having' a central conduit 62 and a pluralityv of circumferential openings 53, 63, the former connecting 'with the tube 58 and the latter with a chamber 64.

Threaded upon the member 6l is a soft rubber distributor 65, having an annular passage 6G, 66 in alignment with the conduits 63, 63, and a central chamber 67 in `alignment with the conduit 62 and having a plurality of outwardly extended conduits `68, 68. The exterior end of passage 65 has slit openings 69, 69 and the exterior end of each conduit 68 has a slit opening 70, acting as click valves.

To assemble the device, the bag,

or bulb,

`element is assembled as previously described,

the member 45 carrying the tube 5l is placed in position and lixedly att-ached to the bag `element by revolving the head 53, thus threading the member 52 and the neclr 31 and compressing the edges of the bag 24 between the shoulders 22 and 7l, the openings in the two latter being in alignment. The brush member 56 is then threaded to the member 49.

The modification shown in Figure ll is similar to the device previously described, the brush member being carried longitudinally instead of angularly to the member 5G.

The operation of my device, assuming that the receptacle 27 contains a tooth liquid or tooth paste, is as follows The exterior member 4l is revolved thus revolving Vthe spiral 32 and moving vthe plunger 35 upwardly. This causes a portion of the yreceptacle contents to be forced through the tube 5l, the tube 58, the tube 62 into the chamber G7 and outwardly through the openings 70, 70 of the conduits 68, `('58. A pressure upon the plates 43, 43 causes a compression of the bag 24, forcing a portion of the contained air to pass through the aligned opening of the members 22 and 7l, through the conduit 50, the openings in the head 53, the conduit 57, the chamber 63, the conduit (it and outwardly through the slits 59, 69. It will thus be seen that both the tooth paste and the air are forced into the hair bristles 80, SO of the brush. If the air be thus forced outwardly during the application of the brush to the teeth, the air current will force the tooth paste into all the crevices and through the spaces between the teeth, thus causing a removal of deposited particles and the application of the paste to all tooth surfaces.

Vfhen the shaving brush ofiny invention is employed, the air ourrentforces the shaving soap lather downwardly around the hair base contacts at the same time removing the air bubbles usually formed at those Uspots.

lVhile I have referred to the brush as having bristles thereon, my device `may be employed with devices having soft rubber projections instead of bristles, and by brushing members7 I mean both vof these forms of device and others of a similar application.

It will thus be seen that the-deviceof my invention possesses hygienic properties of great value.

I do not limit myself to the yparticular size, shape, number, arrangement or materi-al of parts as shown and described as these are given simply as a means forcflearly describing my invention.
